Sorry to hear about the denial letter. As you may know, and for those who don't, you have one year to file a NOD. I also understand and find it notable, that the VA will add on more claims to the original claim...
It happened to me, also.
The VA added unnecessary rabbit trails to my main claim, and then denied them. What a mess. As broncovet mentioned, It can get so frustrating and so complex. And I also agree with Notorious Kelly,... "If you can focus on your foot claim"...
However, When I filed my NOD, I included the items created by the VA, as well. I knew it would add more time. however, since they created a "claim creation date", JMHO, I would suggest you include all items within that one year window.
You and I have, what John999 calls,... "dog claims." Well, since that that die has already been cast, If you don't include any of the 18 VA claims in your NOD, then their gone in 12 months... Who knows what the future will bring. I plan to use one of my absurd VA added claims as a bargaining chip at my finial appeal, if need be...
Also, I would again quote John999, ... Get a lawyer.
Interesting to read about another Vet's claim that got inflated, "frustrating and complex" by the VA adding on. I wounder if it helps the VA raters increase the number of claims cleared and inflate their quotas, as well as any bonuses they may receive??? Odd, indeed.
When I do file my "writ of mandamus" 24 months after the DRO appeal request date. I will include the following at the end of my response letter..
""I take exception to and preserve for appeal ALL errors the VARO may have made or the Board hereafter might could make in deciding this appeal. This includes all legal errors, all factual errors, failure to follow M21-1,all due process errors and any failures to discharge the duty to assist as violation of basic VA laws and regulations within 38 USCS and 38 CFR.""
Then I plan to dig in, get an attorney, and win. Maybe that will bring me peace in my VA matter.
Best wishes in your appeal. Good Luck, you are not alone.
